USRP Daughterboards WBX-LW 120MHZ,X Series only
The WBX-120 is a full-duplex, wideband transceiver that covers a
frequency band from 50 MHz to 2.2 GHz with an instantaneous
bandwidth of 120 MHz. The WBX-120 can serve a wide variety of
application areas including public safety, airband communications,
amateur radio, and ISM. The WBX-120 is compatible with the USRP
X310.
Main Features:
1. Frequency coverage: 50 MHz - 2.2 GHz
2. Maximum bandwidth includes: 120 MHz
3. The WBX RF daughter board contains a full-duplex wideband
transceiver that supports up to 120 MHz of instantaneous bandwidth
4. Serving a wide range of applications: public safety,
communications, amateur radio and ISM
5. The local oscillator's receive and transmit chains operate
independently, allowing for frequency duplex operation
6. The reference for the local oscillator is the master clock from
the USRP, allowing multiple coherent operations
Functional description:
The WBX-LW-40 provides a high-bandwidth transceiver that delivers
up to 100mW of power output with a noise figure of 5 dB. The local
oscillator's receive and transmit chains operate independently and
can be synchronized for MIMO. It is an ideal SDR device for
applications that want to access frequencies in the 50MHz-2200 MHz
range. Applications include WiFi, WiMAX, S-band transceivers and
2.4 GHz ISM band transceivers. Applications include land mobile
communications, marine and aerospace radios; mobile base stations,
PCs and GSM multi-band radios; coherent multi-base radars; wireless
sensor networks; broadcast television; and public safety
management. Applicable to USRP-LW N200, USRP-LW N210, USRP-X310,
USRP-X300.
